In simple terms, there are 4 categories of protists in basic biology characterized by their type of locomotion.
Locomotion by pseudopods or "false feet" is characteristic of ameobas (i.e. <em>Entamoeba histolytica</em>). Locomotion by papillary projections from the cell membrane called "cilia" is characteristic of <em>Paramecium </em>species. Locomotion by whip-like structures that propel the organism called "flagella" is characteristic of <em>Euglena </em>species.

Lastly, protists that do not have locomotive organelles are exemplified by <em>Plasmodium </em>species, the etiologic agent of malaria.
Answer:
THE CELL RECEPTOR DETERMINES WHICH CELL RESPOND TO AN HORMONE.
Explanation:
In the endocrine system, the hormones are usually released into the blood stream from where they traveled to their target organs. Even though the hormones meet a lot of cells on their way, they do not bind with just any cell. Hormones bind specifically to cells that have receptors that is meant specifically for the hormone. The cell receptor enables the binding together of the hormone and the cell membrane or the cell surface. After the binding, the hormone then elicit the needed response in the cell.
I think that there is abundant sunlight in the intertidal zone, which regulates the temperature and prevents the organisms from too cold environment. But, sometimes such high temperature also becomes a problem and the living organisms in the zone, are, therefore, adapted to survive at high temperatures,So they can Live in the envorionment.
I hope this helps
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
